  • Chapter 3: Design an Interconnected Street System
    Chapter 3: Design an Interconnected Street System [Figure 3.1 in margin near here] Street systems either maximize connectivity or frustrate it. North American neighborhoods built prior 1950 were rich in connectivity, as evidenced by the relatively high number of street intersections per square mile typically found there.1 Interconnected street systems provide more than one path to reach surrounding major streets. In most interconnected street networks two types of streets predominate: narrow residential streets and arterial streets. In this book, for reasons explained in chapter two, we call these arterial streets in interconnected networks “streetcar” arterials. On the other end of the spectrum are the post WWII suburban cul-de-sac systems where dead end streets predominate and offer only one path from home to surrounding suburban arterials. This cul-de-sac-dominated system can be characterized as dendritic or “treelike”, the opposite of the web of connections found in interconnected systems. Streets in this system all branch out from the main “trunk”, which in Canadian and U.S. cities is usually the freeway. Attached to the main trunk of the freeway are the major “branches”, which are the feeder suburban arterial streets or minor highways. These large branches then give access to the next category down the tree, the collector streets or the minor branches in the system. Collector streets then connect to the “twigs and branch tips” of the system, the residential streets, and dead end cul-de-sacs. The major advantages of the interconnected system is that it makes all trips as short as possible, allows pedestrians and bikes to flow through the system without inconvenience, and relieves congestion by providing many alternate routes to the same place.

  • Line Structure Representation for Road Network Analysis
    Line Structure Representation for Road Network Analysis Abstract: Road hierarchy and network structure are intimately linked; however, there is not a consistent basis for representing and analysing the particular hierarchical nature of road network structure. The paper introduces the line structure – identified mathematically as a kind of linearly ordered incidence structure – as a means of representing road network structure, and demonstrates its relation to existing representations of road networks: the ‘primal’ graph, the ‘dual’ graph and the route structure. In doing so, the paper shows how properties of continuity, junction type and hierarchy relating to differential continuity and termination are necessarily absent from primal and dual graph representations, but intrinsically present in line structure representations. The information requirements (in terms of matrix size) for specifying line structures relative to graphs are considered. A new property indicative of hierarchical status – ‘cardinality’ – is introduced and illustrated with application to example networks. The paper provides a more comprehensive understanding of the structure of road networks, relating different kinds of network representation, and suggesting potential application to network analysis. Keywords: Network science; Road hierarchy; Route structure; Graph theory; Line structure; Cardinality 1 1 Introduction Road network structure is routinely interpreted in terms of the configuration of roads in structures such as ‘trees’ or ‘grids’; but structure can also be interpreted in terms of the hierarchical relations between main and subsidiary, strategic and local, or through and side roads. In fact, these two kinds of structure – relating to configuration and constitution – are in some ways related. However, despite the proliferation of studies of road network structure, there is not a consistent basis for representing and analysing this dual nature of road network structure, either within traditions of network science or network design and management.

  • A Four Level Road Hierarchy for Network Planning and Management
    Eppell, V.A.T. (Tony) and McClurg, Brett A and Bunker, Jonathan M (2001) A four level road hierarchy for network planning and management. In Jaeger, Vicki, Eds. Proceedings 20th ARRB Conference, Melbourne. A FOUR LEVEL ROAD HIERARCHY FOR NETWORK PLANNING AND MANAGEMENT V.A.T. Eppell, J.M. Bunker and B.A. McClurg Eppell Olsen & Partners Eppell Olsen & Partners has been at the forefront of developing and applying road hierarchy concepts throughout Queensland. One of the objectives of such application is to assist with the management of the road network. Tony Eppell is a director of the firm and has been instrumental in the development of road hierarchy concepts and the application of such in diverse areas. He has presented numerous papers on the subject since 1980. Jon Bunker and Brett McClurg are associates within the firm and have both been involved in the development and application of road hierarchy principles to areas such as Ipswich, Maroochydore and Mackay. ABSTRACT A road hierarchy has, for some time, been accepted as one of the important tools used for road network and land use planning. It is a means of defining each roadway in terms of its function such that appropriate objectives for that roadway can be set and appropriate design criteria can be implemented. These objectives and design criteria are aimed at achieving an efficient road system whereby conflicts between the roadway and the adjacent land use are minimised and the appropriate level of interaction between the roadway and land use is permitted. The introduction of a four level road hierarchy, as presented herein, expands the use of the road hierarchy as a tool for a broad spread of uses ranging from network/land use planning to asset management.

  • A National Road Hierarchy – Are We Ready?
    A National Road Hierarchy – Are We Ready? Andrew G. Macbeth , BE, MEng, CPEng, FIPENZ (Civil) Director, ViaStrada Ltd Level 6, Link Centre, 152 Hereford St PO Box 22 458, Christchurch, New Zealand Phone (03) 343 8224; 027 2929 888 [email protected] www.viastrada.co.nz Abstract Functional road classification systems or road hierarchies are widely used in all aspects of traffic planning, traffic operations and road asset management. Considerable effort should be invested to keep them current, relevant and consistently applied within and across jurisdictions. With increasing emphasis being placed in New Zealand on cost-effective and equitable management of transport infrastructure and sustainable transport systems, road hierarchies should be better designed and implemented than is currently the case. This paper identifies and compares a variety of functional road hierarchies from both the national and local sectors, including those used by Land Transport New Zealand, Transit New Zealand and six metropolitan areas. Many of the systems analysed use traffic volumes as indicators of road class but widely different definitions exist. Besides traffic volumes, the hierarchies have a number of criteria used to classify roads, although these are not explored in any detail in this paper. The paper makes a case for reviewing New Zealand’s various functional road hierarchies to develop a road hierarchy for application across the country. Rational transport planning and traffic engineering decision making will be greatly enhanced by such a move. New Zealand is a small enough country that a national road hierarchy could be developed with relative ease, whereas other, larger countries will have much greater difficulty aligning the systems of many more agencies.
